TYPE-WRITING MACHINE.

- Specification of Letters Patent.

Patented June 8-, 1915.

To all whom it may concern:

Be it known that 'I, VVILLIAM W. PHILLIPS, a citizenof the UnitedStates, residing at St. Louis, Missouri, have invented a certain new anduseful Improvement in Type-Writing Machines, of which the following isa, full, clear, and exact description, such as will enable othersskilled in the art to which it a pertains to make and use the same.

,T is invention relates to typewriting machines, and particularly tomachines of the design in which the carriage is provided at one end witha device that the operator grasps to actuate the line-spacing mechanismand to move the carriage laterally of the .machine back to its startingposition. In some typewriting machines this combined line-spacing andcarriage-restoring device is located at the left hand end of thecarriage, and in other typewriting machines it is located at the righthand end of the carriage. Consequently, some operators prefer one typeof machine merely because it is more convenient to use the left hand tooperate the line-spacing mechanism and restore the carriage to startingposition, and other operators prefer the other type of machine becausethey find it more convenient to use the right hand to operate theline-spacing mechanism and to restore the carriage to starting position.

The main object of my invention is to provide a typewriting machinewhich is so designed that the operator can use either the right or theleft hand to operate the linespacing. mechanism and restore the carriageto starting position, the carriage of the machine being equipped withtwo separate and distinct devices located adjacent the opposite ends ofthe carriage for effecting these operations.

Another object of my invention is to provide an attachment for anUnderwood typewriting machine that can be applied to same easily, so asto enable the operator to-use the right hand as Well as the left hand tooperate the line-spacing mechanism and move the carriage laterally backto starting position.

Other objects and desirable features of my invention will be hereinafterpointed out.

Figure 1 of the drawings is a top plan view of a portion of the carriageof an Underwood typewriting machine equipped with my attachment; Fig. 2is a transverse vertical sectional View taken on the line 2-2 of Fig. 1,looking in the direction indicated by the arrow; and Fig. 3 is avertical sectional view taken on the line 33 of Fig. 1.

Referring to the drawings which illustrate the preferred form of myinvention, A-

' at its front end with an upwardly projecting finger piece 3. The partsabove mentioned are of the usual construction embodied in the standardUnderwood typewriting machine now in general use.

In order that an operator may use her right hand as well as her lefthand to actu ate the line-spacing mechanism previously referred to, andalso move the carriage laterally back to starting position, I have,

equipped the carriage A with a device B provided with a finger piece 4that is located at the right hand end of the carriage, said device Bbeing so constructed and arranged that it will actuate the lever 3 whenthe operator moves said device to the right. The

device B preferably consists of a bar arran ed at the rear of the frontcross member of the carriage A, and on the left hand end of said bar isa projection 6 that engages the bell crank lever 3 and actuates samewhen said bar is moved to the right, looking at Fig. 1. The bar B ismounted on the carriage in such a manner that it can move relatively tothe carriage a sufficient distance to actuate the bell crank lever 3,but after said lever has completed its feeding stroke the carriage Awill start to move laterally in the direction in which the operator ismoving the bar B. When the operator releases the bar B or removes herfinger from the finger piece 4 at the right hand end of said bar. thespring 6 that forms part of the linespacing mechanism exerts pressure onthe lever 3 and restores it to normal position, and said lever, in turn,restores the bar B to normal position.

Any suitable means may be employed for mounting the bar B on thecarriage of the machine, the means herein shown consisting of a bolt orstud 7 in the front cross member of the carriage that projects through ahorizontally disposed elongated slot 8 in the right hand end of the bar,and a guide or strap 9 at theleft hand end of the carriage, throughwhichthe bar B passes, as shown in Fig. '2, said strap 9 being carriedby a re movable plate 10 on the carriage 4 under which the forwardlyprojecting arm of the lever 3 ,passes. The carriage of the standardUnderwood machine is equipped with a removable plate similar to theplate 10 of the machine herein shown, except that it is not providedwith a guide or strap 9 and the front cross member 5 of the carriage ofa standard Underwood is also provided with a screw located in the sameposition as the bolt 7 of the machine herein illustrated. Consequently,in applying my attachment to an Underwood machine, it is not necessaryto form any additional holes in the carriage or cut'the carriage, but,on the contrary, it is only necessary to substitute a bolt 7, a plate 10of the particular design herein shown and arrange the bar B in operativeposition. The intermediate portion of the bar B is bent downwardly at11, as shown in Fig. 2, so that it will not interfere with the envelopguide 12 that is usually formed on the rear side of'the front crossmember of the carriage of an Underwood machine.

While I have herein illustrated my invention applied to an Underwoodmachine, I wish it to be understood that the invention is not limited toany particular type or make.

of typewritin machine, or to a machine in which the devlce that actuatesthe line-spacing mechanism and restores the carriage to startingposition is located at the left hand end of the carriage, for my broadidea consists in a typewriting machine in which the carriage is providedwith two separate and distinct means, located at the right and left handends of the carriage for operating the line-spacing mechanism and forrestoring the carriage to starting position, so that the operator canuse either hand for performing these operations.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. In a typewriting machine provided with a line-spacing mechanism and alever for operating the same arranged adjacent one end of the carriageof the machine, a shiftable bar extending across the front portion ofsaid carriage, one end of said bar being sup ported adjacent said leverby means of the end frame of the carriage and provided with a projectionthat lies behind said lever, the opposite end of said bar being providedwith a handle or finger piece and supported on the front portion of saidcarriage by means of a slot and pin connection.

2. In a typewriting machine, a line-spacing mechanism and a lever foractuating the same arranged at one end of the carriage, a shiftable barhaving one end slidably mounted on the end frame of the carriageadjacent said line-spacing mechanism, a guide on said carriage forpreventing lateral displacement of said bar, a'projection on one endofsaid bar that is adapted to engage said lever, a finger piece on theopposlte end of said bar, and a slot and pin connection between said barand said carriage adjacent said finger piece. v,

3. An attachment for an Underwood typewriting machine, consisting of abar that is adapted to be reciprocatingly mounted on the front crossmember of the carriage of themachine for operating the lever onsaidcarriage that is used for actuating the line-- spacing mechanism, andremovable. devices that are adapted to be connected to the carriage forsupporting and guiding said bar, said barbeing provided at one end witha finger piece and at its opposite end with a portion for engaging saidlever when the bar is shifted in one direction.

In testimony whereof I hereunto alfix my signature in the presence oftwo witnesses, this 17 day of September 1914. Y WILLIAM W. PHILLIPS.
